Pauline McCallion, editor of Your Mortgage, said: "The mortgage market is constantly changing, no more so than in the past five years. Yorkshire Bank has demonstrated to our judges that it has, not only acknowledged, but also been at the forefront of these changes, particularly in the development of flexible mortgages.
"This coupled with the service and local knowledge it offers mortgage customers has made it a winner."
In addition to receiving the "Best Regional Mortgage Lender" award, Leeds-based Yorkshire Bank was highly commended in for its offset mortgage offering.
Offset mortgages enable customers to reduce their interest payments when compared to traditional mortgages - sometimes saving many thousands of pounds - and clear their home loan much sooner by taking into account any savings or credit balances they may have.
Also collecting an award was Yorkshire's sister bank, Clydesdale. Clydesdale Bank was named "Best Mortgage Lender in Scotland" by Your Mortgage for the fourth year running.
Both banks received their prizes at the Your Mortgage Awards in London on November 15.
Gary Lumby, head of retail banking at Yorkshire Bank, said: "Being recognised in this way for the quality of our products and service gives a tremendous boost to our staff and demonstrates Yorkshire Bank's commitment to our customers both locally and nationally."
